However, the method of using the standard measuring tools such as volumetric flasks, measuring cylinders and the like to calibrate a large-volume water tank or a large-volume water tank first and then calibrating a large-volume container with the water tank or the large-volume water tank usually causes great operation errors and implementation difficulties for calibration work due to frequent observation of scale marks, repeated pouring of calibration solution, deformation of the water tank and the like. Therefore, a large number of cylinders for calibration, which have fixed volume and can quickly fix the volume, are developed, and the method has important significance for realizing quick and accurate calibration of the volume of a large-volume container.
